摘要
为了探讨信号交叉口违章行人对左转车辆运行的影响,以宁波市通途路与新芝路交叉口为研究对象,通过对基础数据的采集与分析,使用SPSS软件拟合车头时距与行人违章数之间的曲线关系,并利用Webster法和VISSIM仿真软件对交叉口重新信号配时优化。结果表明:违章数与车头时距拟合关系符合幂函数形式;信号配时优化后交叉口平均延误和排队长度分别降低7.6s和7.7m,相当于整个交叉口的11.8%和18.6%。此研究对提高交叉口的运行效率有一定意义。
In order to investigate the influences of illegal pedestrian crossing on the running of left-turning vehicles at the signal intersection with TongTu and XinZhi road intersection as an example, the present study, based on the basic data collection and analysis, employs SPSS software to fit the curvilinear relationship between the headway and the pedestrian peccancy and Webster method as well as VISSIM simulation software to optimize the signal timing at the intersection. The results show that the fitting relationship between the headway and the pedestrian peccancy lines with the logarithmic function and the average delay and the queue length after the signal timing is optimized are reduced to 7.6s and 7.7m, equivalent to 11.8% and 18.6% of the entire intersection, which helps improve the operating efficiency of the intersection.
